The three periods of unlawful detention are believed to have come after lawful prison terms, following which the Home Office kept him in while his deportation was considered.

Here's an idea:- don't keep him in prison beyond his sentence while you make up your minds.

Problem solved.

Allowing states to detain people willy nilly is a dangerous road to go down - the fine wasnt enough, those responsible for making the decisions should have been prosecuted

If I falsely imprisoned someone then I'd be prosecuted and would have to pay with my liberty as well ass a heap of cash to the person to whom I'd locked up. Processes are there for a reason, to be followed. May discovered this when she buggered up the deportation of Hamzah and others because she wouldn't apply the necessary due diligence to the law and had to do it again properly.

This toerag needs to be deported but the people who are doing it need to do their jobs rather than a personal interpretation of the laws involved that continually costs the country money because of ignorance or laziness.
